〔産業上の利用分野〕
本発明は耐摩耗性がすぐれ、切れ味が従来になく持続す
る安価な、はさみのサーメット超硬合金刃先部材に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cermet cemented carbide cutting edge member for scissors, which has excellent wear resistance, maintains sharpness longer than ever before, and is inexpensive.
従来の金属製はさみは鉄合金、ステンレス鋼などを鍛造
、又は鋳造により製作するもので、刃先部分を焼入れ硬
化させる場合もあるが、短時間の使用で刃先が摩耗して
切れ味が落ちる。Conventional metal scissors are manufactured by forging or casting iron alloys, stainless steel, etc., and the cutting edges are sometimes quenched and hardened, but after short periods of use, the cutting edges wear out and lose their sharpness.
このため、切れ味を長く保つため高硬度鋼を使用するこ
ともあるが加工が難しいので高価なものとなる。そこで
刃先のみに超硬合金を溶接したり、蒸着法で炭化物、窒
化物等の超硬材料の皮膜を付けたりセラミックを接着又
は溶射する方法等が考えられている。For this reason, high-hardness steel is sometimes used to maintain its sharpness for a long time, but it is difficult to process and therefore expensive. Therefore, methods such as welding cemented carbide only to the cutting edge, applying a film of carbide, nitride, or other superhard material by vapor deposition, or bonding or spraying ceramic are being considered.
然し乍ら刃先に超硬合金を刃先に溶接する方法では加工
が複雑なため高価となり、超硬材料の蒸着皮膜は教則以
下の厚さの皮膜しかつけられず摩耗したとき研摩再生が
できない。However, the method of welding cemented carbide to the cutting edge requires complicated processing and is expensive, and the vapor-deposited coating of carbide material can only be applied to a thickness that is less than the thickness specified in the instructions, and cannot be re-polished when worn.
又、セラミック刃先は少しの衝撃で欠けるという欠点が
ある。Additionally, ceramic cutting edges have the disadvantage of chipping with the slightest impact.
本発明はこのような欠点を解決するためにサーメット超
硬合金を刃先部分に数１０〜１００μｍの厚さに形成さ
せるもので万一刃先の切れ味が落ちた場合でも研削によ
り再生することは容易であるつ
また、本発明によれば、はさみ本体は軟鋼や軽合金等の
安価な金属が使用できるため経済的にも効果がある。In order to solve these drawbacks, the present invention forms a cermet cemented carbide at the cutting edge with a thickness of several tens to 100 μm. Even if the cutting edge loses its sharpness, it can be easily regenerated by grinding. In addition, according to the present invention, the scissors main body can be made of inexpensive metal such as mild steel or light alloy, which is also economically effective.

強固に付着する。For example, WC-Co (25%) thermal spray powder is sprayed onto at least the portions of the scissor bodies 1 and 2 made of soft iron, which will become the cutting edges, to form the cutting edge members 3 made of cermet cemented carbide. If a thermal spray coating such as N1-AJ is formed as a base treatment for this cermet cemented carbide thermal spraying, the cermet superalloy coating will adhere more firmly.
